JOHN C. MORGAN, OF LOS ANGELES, CALIFORNIA.

ELECTRIC GENERATOR.

Application filed April 25, 1916.

To all whom it may concern:

Be it known that I, JOHN C. MORGAN, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in ElectricGenerators, of which the following is a specification.

The invention relates to electric flash lamps, and more particularly tothe class of portable electric flash lamps.

The primary object of the invention is the provision of a lamp of thischaracter wherein it can be carried upon the person and the use of drybatteries eliminated, the lamp being under perfect control of theoperator and adaptable for use by firemen, miners, oil inspectors or anyperson.

Another object of the invention is the provision of a lamp of thischaracter wherein the construction thereof is novel in form to assurethe perfect working of the same and is convenient for use.

A further object of the invention is the provision of a lamp of thischaracter wherein the electric generator for the current is actuated bya spring adapted to be wound by hand, the speed of rotation of thearmature of the generator being controlled automatically, and thecurrent to the lamp can be opened or closed at two distinct points withdespatch.

A still further object of the invention is the provision of a lampstructure of this character which is simple in construction, readily andeasily applied to and removed from the person, strong, durable,economical, reliable and eflicient in operation and inexpensive inmanufacture.

Other objects will be in part obvious and in part hereinafter set forth.

The invention accordingly consists in the features of construction,combination of elements and arrangement of parts which will beexemplified in the construction hereinafter described, and the scope ofthe application of which will be indicated in the appended claims.

In the accompanying drawings:

Figure 1 is a plan view of the box, with the cover section removed,showing therein the spring, gearing and generator;

2 is a sectional view on the line 44 of Fig. 3;

Specification of Letters Patent.

Patented June 12, 1917.

Serial No. 93,530.

Fig. 3 is a sectional view on the line 55 of Fig. 3.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawings.

B designates a box or case in which is arranged a spring actuated motor15 having a drive shaft 16, the spring 17 of the motor 15 being woundthrough the medium of a handle 18 which is connected to the drum of themotor 15, the handle at the point of connection with the drum beinfitted with a ratchet 19 which is engaged y means of a spring-heldratchet pawl 20 suitably pivoted in the box or case B, and upon theshaft 16 is mounted a driven gear 21 which meshes with one of a train ofgears 22, the shaft 23 of which is suitably journaled in the side Wallsof the box or case. Another gear of the train ofgearing 22 meshes with apinion 24 fixed to a governor shaft 25 which is also journaled in theside walls of the box or case, and this governor shaft has mountedthereon a centrifugal governor 26, the brake disk 27 of which is actedupon by means of a shoe 28 so that the speed of rotation of the governorshaft 25 canbe varied. The shoe 28 has loosely connected thereto a feedscrew 28 which is threaded in the wall of the case or box.

Fixed to the governor shaft 25 is a driven gear 29 which meshes with apinion 30 fixed to the shaft of the armature 31 of an electric generator32, the brush 33 of which is pivotally mounted, and this brush has abinding post 34 to which is connected one of the leads 14 of thecircuit, while the other brush 35 is in the form of a resilient movablemember and forms part of a normally open switch 36 to which is connectedthe other lead 14 of the circuit.

Suitably mounted within the case is the rocking operating lever 37 towhich is loosely connected a switch closing arm 38, the same beingpivoted at 39 and is formed with a head 40 which is adapted to act uponthe movable member 35 of the switch 36 for the closing thereof onactuating the lever 37 which extends without the case and carries abutton terminal 41 so that it can be readilymanipulated.

Formed on the gear 29 is a brake rim 42 with which is adapted to beengaged a brake shoe 43 mounted upon an operating lever 44 which islocated interiorly of the box or casing A and mounted in any suitablemanner, the lever 44 being dc ended without the case or box B and hastlie terminal button 45 for its convenient operation.

The spring 17 of the motor 15 is wound by hand and on the releasing ofthe brake 43 the generator 32 will be actuated for the source ofelectric current through the leads 14 to the lamp, the governor 26 beingdesigned to control the speed of rotation of the generator.

From the foregoing description, taken in connection with theaccompanying drawings the construction and operation of the hereindescribed flash lamp will be readily apparent and, therefore, a moreextended explanation has been omitted.

Having thus described my invention, I claim: I

1. The combination with a case, a motor arranged interiorly of the caseand having a drive shaft, an electric generator within the case andhaving an armature, a pivotal brush Working against the armature, abinding post supporting said pivotal brush and adapted to be connectedwith one wire of an electric circuit, a resilient brush working againstthe armature, a normally open switch having one part carried by the caseand the other part carried by the resilient brush, a binding post on thepart of the switch carried by the case and adapted to be connected withthe other wire of the electric circuit, a lever pivoted within the caseand projected exteriorly thereof for operation upon the part of theswitch carried by the resilient brush to bring said part into engagementwith the other part of the switch on the casefor closing the electriccircuit, and connections between the motor and generator.

2. The combination with a case, a motor arranged interiorly of the caseand having a drive shaft, an electric generator within the case andhaving an armature, a pivotal brush working against the armature, a binding post supporting said pivotal brush and adapted to be connected withone wire of an electric circuit, a resilient brush working against thearmature, a normally open switch having one part carried by the case andthe other part carried by the resilient brush, a binding post on thepart of the switch carried by the case and adapted to be connected withthe other wire of the electric circuit, a lever pivoted within the caseand projected exteriorly thereof for operation upon the part of theswitch carried by the resilient armature to bring said part intoengagement with the other part of the switch on the case for closing theelectric circuit, connections between the motor and generator, agovernor shaft included in the connection, a centrifugal governor onsaid governor shaft and having a brake disk, a shoe pivoted within thecase and engageable with the disk, an operating screw connected with theshoe and adjustably threaded in the case from without the same.

In testimony whereof I affix my signature.

JOHN C. MORGAN.
